A/C Compressor Automatic Control
x
The A/C amplifier switches modes between the A/C mode and ECO mode based on the input signal from the
ambient temperature sensor and the air intake mode. When the air intake mode is REC, the system is set to A/
C mode. If during FRESH mode the ambient temperature is low or high, the A/C mode is selected, if it is in the
medium range ECO mode is selected.
x
If the evaporator temperature is at a specific value
during ECO mode, the A/C signal is switched on/
off (magnetic clutch on/off). When the A/C signal
is on/off, the evaporator temperature is
determined based on the signal from the ambient
temperature sensor and the target temperature. If
the target temperature is low, the on/off
temperature is set low, if it is high, the on/off
temperature is set high. If the ambient
temperature is high and increased air conditioning
performance is required, or increased defrosting
performance is required when windows fog easily
due to low ambient temperature, the on/off
temperature is set low. When none of the
conditions above are applied, the on/off temperature is set high. As a result, A/C performance and fuel
economy during A/C operation time have been improved.
Correction
Defroster correction
x
When the defroster switch is turned on, the system is switched to A/C on mode to improve defrosting.
MAX HOT and MAX COLD correction
x
When the set temperature is at 32.0 , the system is set to A/C off mode, when it is at 18.0 , it is set to A/C on
mode.
A/C Compressor Manual Control
x
The A/C on mode or A/C off mode can be selected by operating the A/C switch.
